摘要： Disclosed is a crosswalk system according to various embodiments comprising an infrastructure including a communication device, a vehicle communicating with the infrastructure, and an indicating device electrically connected to the infrastructure. The infrastructure may detect an external object within a predetermined area through at least one sensor, obtain a location of the vehicle through the communication device, and based on the detected external object and the obtained position of the vehicle, transmit to the indicating device a signal requesting provision of information related to whether it is possible to cross the predetermined area from the external object or the vehicle. Other various embodiment may be implemented.

摘要： The present invention relates to a small dipole antenna, and more specifically, to a small dipole antenna comprising a balun, a meander line, and a cap covering the meander line as a whole, wherein both sides of the dipole antenna are provided with the meander line to minimize the overall size of the dipole antenna. The small dipole antenna according to one embodiment of the present invention obtains resonance frequency adjustment characteristics by filling a gap between the arrangement of the meander line disposed on the both sides of the dipole antenna on the basis of the balun and the meander line, and adds a short circuit between the meander line to achieve impedance matching and minimize the overall size of the dipole antenna structure at the same time, thereby having the effect of ensuring tractability of antenna operation regardless of external conditions when measuring electromagnetic wave performance.
